Help needed with C program + Mysql

2002-02-28 Thread Villarroel Nuñez Alejandro Arturo

I have defined a Mysql table with some integer variable, I can put
NULL values in these elementes, but when I user mysql_fetch_row, if there's
some integer field with NULL value, the program fails with core dump.
Where's the problem?
Thanks in advance.

Hi.

The char* to the field value will be NULL (in the C meaning), if the
value is NULL (in the SQL meaning). The reason for your core dump is
probably a missing check before you treat the NULL pointer as string.

Bye,

Benjamin.
